Abstract
The amination of 2-ethoxy-3,4-dihydroquinoline by phenacylammonium salts has been studied. The products of this reaction are 2-phenacylamino-3,4-dihydroquinoline hydrochlorides and these are converted to 1-aryl-4,5-dihydroimidazo[1,2-a]quinolines by refluxing in aqueous solution with a catalytic amount of HCl.
